WATER AND OIL VAPORIZER AND BURNER.

SPECIFICATION forming part of Letters Patent No. 392,510, dated November6, 1888. Application filed January 13, 1887. Serial No. 224,307. (Nomodel.)

To all whom it may concern:

Be it known that I, EDWIN D. GRANGER, a citizen of the United States,residing at Omaha, in the county of Douglas and State of Nebraska,haveiuvented certain new and useful Improvements in Water and OilVaporizers and Burners, of which the following is a specification,reference being had therein to the accompanying drawings.

Myinvention relates to certain new and useful improvements in stoves andheating devices which employ oil and water as fuel. Said oil and waterbeing vaporized in a heated retort forms a combustible vapor which whenlighted will generate a large amount of heat, the object of my inventionbeing to provide acheap, simple, and effective means for generating,igniting, and burning vapor, so that it may be employed for heatingpurposes; and my invention consists in the special construction,combination, and arrangement of the parts, as will be'hereinafter fullyset forth, and specifically pointed out in the claim.

In the accompanying drawings,which illustrate my invention, Figure l isa side View, partly in section, of an oil and water vapor izer, burner,and heater constructed in accordance with my improvement. Fig. 2 is adetail perspective view of the burner detached, and Fig. 3 is a view,partly in section, showing my improvement as applied in use.

A refers to the outer casing, which is preferably oval in form, thelower portion being tubular, as shown at a, to which portion is suitablyconnected a base, Z),which is mounted on legs. The outer casing, A, maybe provided near its lower end with a suitable door or open ing, throughwhich access can be had to the burner when desired, and between the baseI) and the outer casing, A, may be located a damper, c. The outer orexterior casing is made up of two or more parts which are bolted to eachother, and near the upper portion is located an eseapepipc, d, whichleads, preferably, into a heating-drum, D, of ordinary construction,which is connected by suitable pipes to'a fine or chimney.

The base I) may be of any suitable construction or configuration, and-itis preferably provided with a drawer, I), having registers, as shown.

B refers to the interior casing or vaporizer which corresponds in shapewith the exterior casing, to which it is attached by suitable bolts, 6e. The lower or contracted portion of the vaporizer is screw-threadedboth internally and externally, the internal screw-threads engaging withthe threaded pipe 0, which extends to near. the top of the vaporizer,and this pipe, which is maintained in a vertical position, is providedat a slight distance above the lower end of the vaporizer with aperforation, f, for the purpose, as will be hereinafter described.

The burner D consists of a box or casing which has a perforated top andcentral opening therein, having screw-threads for attach ing the same tothe generator 13. The bottom of this burner-is provided with two ormore.

small openings, g g, and beneath the sameis supported by means of barsh, a pan, D 1n which is placed a quantity of asbestus or other absorbentmaterial which is not destructible by iire.

At the top of the vaporizer B, preferabl immediately above the pipe G,the same i provided with an opening or valveseat whic is closed by asuitable safety-valve, F.

At a suitable distance and a convenien point to the heating-tubes isplaced a tank which is separated into two compartments, thesecompartments being for the reception of oil and water, and to the bottomof this tank is attached, by suitable couplings, pipes E and E, thesepipes passing through the outer casing and into the vaporizer, wherethey terminate near the bottom thereof, and these pipes E and E are eachprovided with cocks z and i, for cutting off or regulating the flow ofliquid from the tanks to the vaporizer.

WVhen it is desired to start the fire, the valve leading to the oil-tankis turned, so as to admit a small quantity of oil to the vaporizer,which will escape through the small hole near the lower end of the pipe0 and finds its way from thence into the burner, from which a smallquantity will escape to the pan D and will be absorbed by theasbestuswick. When the oil absorbed by the wick is lighted, it will heatthe burner and convert all the oil that may be contained therein intovapor. After the oil which has flowed into the burner i:

consumed, which can be ascertained by the color of the flame, whiclnwhenthe oil begins to vaporize, changes from a heavy red to a light blue,the water-valve is then turned, so as to admit water to the vaporizer inabout the proportions of two of water to one of oil, and will be fed tothe vaporizer, which is heated, said heat converting the same rapidlyinto vapor, which rises and isforced out of the pipe Ointo the burner,which is in a highly-heated contion, and is burned as it escapes throughthe perforations in the top of the burner. The heavy particles which arecarried by the vapors will escape through the small perforations in thebottom of the burner and collect in the bottom of the pan. By regulatingthe supply of oil and water the heat can be regulated.

By constructing the parts as hereinbefore described, especially thevaporizer, and having the point thereof downward, larger heatsurfaee isthrown in contact with the flame, and, as the shell of the vaporizer isquite thin, it will be quick to correspond to the heat.

In case the oil and water should be vaporized too rapidly, or anexcessive pressure should be cast on the vaporizer, the valve willelevated so as to relieve said pressure.

This device is applicable to heating and cook stoves, and also forfurnaces for generating a steam, &c., and when desirable the exteriorcasing, A, may be dispensed with, as when the same is employed forcooking-stoves.

What I claim, and desire to secure by Letters Patent, is-

In a device for vaporizing oil and water and burning its vapor, thecombination of a vapor izer consisting of an inverted conical shell, tothe lower end or apex of which a burner is secured, a central pipeconnected to said apex of the conical shell at its lower end, andextending upwardly therein to near the top thereof, and provided with anopening, f, near its lower end, the outer inclosing-shell, A, conformingto the shape of the inner shell or vaporizer, the heating-drum connectedto and supported upon the top portion of the outer shell, the heatersecured to the lower part of said shell, the oil and water tanks, andthe feed-pipes E and E, for feeding oil and water from the oil and watertanks to the inner or vaporizing shell, the said pipes terminating nearthe lower inner portion of the said vaporizing shell or chamber,substantially as described.

In testimony whereof I affix my signaturein presence of two witnesses.
